WEATHER-STRIP 0R DRAFT-EXCLUDER FOR WINDOWS, DOORS, AND THE LIKE.

Application filed October 23, 1913.

To all whom it may concern Be it known that I, Louis JEAN Ln CLAIR, asubject of the King of Great Britain, residing at Moorgate lVorks,Moorfields, London, England, have invented new and useful Improvementsin WVeather- Strips or Draft-Excluders for lVindows, Doors, and thelike, of which the following is a specification.

This invention relates to weather strips or draft excluders especiallyapplicable to sliding frameless windows for railway carriages and othervehicles, but also appli cable to the doors of railway vehicles or toother doors or windows or thelike.

The sliding windows of railway and other carriages are frequentlyarranged in guides which are of considerably greater width at the lowerparts than the sliding window so as to allow the lower edge of thewindow, when being closed, to be moved over a fence plate, for thepurpose of excluding wind and rain; in another class of window theguides are made of approximately the same width as the thickness ofthesliding sash or the window, cushions, pads orthe like being arrangedin the window frame, at the bottom of the sliding window, for preventingthe entrance of wind and rain. In this latter class of window, which isthe class to which my invention is especially applicable, the pads orcushions are frequently made of felt or other material which after acertain amount of use fails to form a tight joint and which,furthermore, is more or less injuriously affected by climaticconditions, and also, in some countries, by insects, and one of the mainobjects of this invention is to provide, in conjunction with a window ofthe kind in question, improved means for excluding wind and rain.

According to my invention I'provide what may be termed a laminated barwhich is preferably made of a series of thin plates of metal, vulcaniteor other material, of a substantially imperishable nature, laid togetherto form a brushing edge and adapted to bend slightlyin the direction ofits width to form a tight joint against a window or door when in contactwith it.

To enable my invention to be fully understood I will describe the sameby reference to the accompanying drawing, in which Figure 1 is asectional elevation through the lower part of a sliding window andSpecification of Letters Patent.

framing having my improvements in connectlon with it. Fig. 2 is a viewsimilar to Fig. 1, but showing the sliding window in a differentposition. Fig. 3 is a section on the line 3 3, Fig. 1. Fig. 4 is a viewdrawn to an enlarged scale of the draft excluder arranged in accordancewith my present invention, and Fig. 5 is a view similar to Fig. 4, butillustrating a slight variatlon, and Fig. 6 is a sectional viewillustratmg the application of my invention to a door.

a indicates the framing around the window opening of a carriage and Z)the frameless window, sliding in grooves 0, 0 formed in the framing a atthe sides of the window opening, the said window at its lower part beingfixed to a grooved bar (Z of metal. which in the drawing is representedas be mg carried at the upper'end of a system of levers of the kindreferred to in the specification of former Letters Patent granted to meNo. 6181 of 1911, but which may be adapted to be supported by any othersuitable means.

6, e are strips of felt or other packing material arranged in the.grooves in which the window slides and f, f are wooden strips againstwhich'springs g, g bear with sulficient pressureto hold the glass 6 incontact with the strips 6 but not sufficient to prevent the window frombeing readily moved.

it is the weather strip or draft excluder constructed according to myinvention, the

;said strip being composed of a series of thin plates 7,, a, a,advantageously made of copper or other relatively soft metal laid oneupon another and secured together. In practice the several plates 2', z'are advantageously secured in a holder 9' provided with a cover plate 70of metal, such as sheet brass having a certain amount of elasticity, sothat it will be capable of returning to its normal position afterdisplacement. This laminated bar it is arranged with its brushing edgeextending slightly be yond the plane through which the lower part of thewindow moves and at an angle of say 15.", as shown in Fig. 2, so thatwhen the window is moved to its closed position, as shown in F ig. 1,the plain face of the bar 03, (or the lower part of the sash, if the window is mounted in a sash) by coming into contact with the brushing edgeof the said laminated bar, will bend the latter slightly as indicated inFig. 1 and thus produce the necessary contact between the Window and thesaid laminated bar to form a weather proof joint. The brushing edge ofthe laminated bar h is beveled so that the edges of all the plates 2',2' will lie in contact with the bar cl.

Z is a strip of felt or other material that is placed on the windowframing immediately opposite to the laminated bar 71., so that thewindow will be supported to enable it to bend the said laminated bar tothe re quired extent to form a tight joint.

In some cases my improved laminated bar may be fixed on the inside of awindow only to form a draft excluder.

Fig. 5 shows the laminated bar provided with a rigid cover plate m whichextends nearly to the edge of the said bar above the spring cover plate70.

Although I have described my invention as applied to a sliding window itis obvious that it can be used in connection with a hinged door. In Fig.6 which illustrates such an arrangement, n indicates the door frame and0 the door, the laminated device h being shown as arranged in a recesscut in the door frame and the brushing edge arranged to project slightlybeyond the surface of the said frame so that the edge of the door willclose against it.

It will be obvious that in certain cases the arrangement hereinbeforedescribed may be reversed, that is to say, the laminated bar instead ofbeing fixed to a rigid part can be applied to the movable part andadapted to cooperate with a plain surface on the rigid part.

Claims.

1. A weather strip or draft excluder composed of a series of thin metallaminae or plates fixed together and designed to be applied inconnection with a window, door or the like, in such a manner, that theclosing of the said window, door or the like will cause the said weatherstrip or draft excluder to cooperate with a plain surface, against whicha joint is to be made and slightly bend the said strip, substantially asdescribed.

2. A weather strip or draft excluder wherein a series of thin metalplates capable of bending slightly are laid one against another andsecured in a holder, substantially as described.

3. In a weather strip or draft excluder, the combination with a seriesof thin metal plates, of a plate of spring metal and a holder in whichthe said thin plates and spring plate are fixed.

4:. In a laminated weather strip or draft excluder, the combination witha series of thin soft metal flexible strips, of a cover plate of springmetal, a holder in which the said plates are fixed and a projecting partabove the level of said plates adapted to cover or shield the same.
